Preheat your oven to 325°F (163°C). Generously grease and flour a 12-cup bundt or tube pan. Set aside.
In a large mixing bowl, cream together the softened butter, cream cheese, shortening, and vegetable oil until smooth and fluffy (about 4–5 minutes on medium-high speed).
Gradually add the granulated sugar, continuing to beat until the mixture is light and creamy (about 5–7 minutes).
Beat in the eggs, one at a time, mixing well after each addition to ensure full incorporation.
Stir in the vanilla extract, lemon extract, and butter vanilla emulsion.
In a separate bowl, whisk together the flour, salt, and baking powder.
Gradually add the dry ingredients to the batter, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined do not overmix.
Pour the batter evenly into the prepared pan. Bake at 325°F (163°C) for 1 hour 15 minutes to 1 hour 25 minutes, or until a toothpick inserted into the center comes out clean.
Remove from oven and allow the cake to cool in the pan for 10–15 minutes. Carefully invert onto a wire rack and allow to cool completely.
